Integrated self-buffering loading device for explosive safety test

The invention discloses an integrated self-buffering loading device for an explosive safety test. The disclosed device comprises a table top seat, a gun barrel and a target box, the gun barrel and the target box are fixedly installed on the table top seat, the axial direction of the gun barrel and the axial direction of a cavity of the target box are the same direction or coaxial, meanwhile, a bullet inlet of the target box is located at the bullet outlet end of the gun barrel, and a distance is formed between the gun barrel and the target box in the axial direction. Under the action of air pressure, the bullet moves towards the bullet outlet in the gun barrel movement channel, the end part provided with the pressure sensor is ejected from the bullet outlet to move into the target box cavity, the to-be-measured sample in the cavity is impacted, the impact pressure is measured, and meanwhile, the tail part of the bullet is left in the gun barrel; and then the bullet rebounds into the gun barrel under the count
